DCOLLECT Type V Record

This table shows the record layout for type V DCOLLECT records
(Volume Information).

Purpose: The DFSMS Data Collection Facility (DCOLLECT) is a function of access method services. DCOLLECT collects stored data set, volume and policy values into a sequential file you can use as input to other programs or applications.

The DCOLLECT output file consists of a number of different record types.

Type V records contain volume information. One of these records is created for each volume scanned. These records are collected when the VOLUME, or STORAGEGROUP, or both parameters are selected, and the NOVOLUMEINFO parameter is not specified. The record type for this record is V.

 


It's easy to report on DCOLLECT type V records! (Jump to sample reports)

DCOLLECT Spectrum WRITER
We have a low-cost 4GL report writer especially for DCOLLECT files. It's called Spectrum DCOLLECT Reporter.

Spectrum DCOLLECT Reporter handles the difficult DCOLLECT record parsing for you automatically. You just specify which fields you want to see.

Spectrum DCOLLECT Reporter also converts the arcane date and time fields and reformats them into an attractive report. It defines the individual bit flags for easy testing or printing.

Plus, Spectrum DCOLLECT Reporter can export DCOLLECT data as comma delimited files to use on your PC.

Sample Disk Volume Statistics Report
from DCOLLECT Type V Records


The sample DCOLLECT report below was created with Spectrum DCOLLECT Reporter, Pacific Systems Group's low-cost 4GL DCOLLECT report writer.

It reads as input the DCOLLECT file and selects just the type V (Disk Volume Information) records. (See DCOLLECT type V record layout.)

Our report shows the volume's total capacity, free capacity and percent of free capacity. It also shows the fradementation index. We examine the "public" and "private" bit flags in the record; we use them to set a user-friendly type field to show in the report.

All of this with just a few lines of code!
